Protocol Independent Multicast 2 – Networking – 350-601 Study Guide

The ASM mode is the default mode when you configure RPs. Bidirectional shared trees (Bidir) is a PIM mode that, like the ASM mode, builds a shared tree between receivers and the RP but does not support switching over to a source tree when a new receiver is added to a group. In the Bidir […]

Spot – Designing for Cost Efficiency – SAP-C02 Study Guide

Spot Perhaps the most cost-effective pricing model out there, Spot Instances can provide up to 90% cost savings compared to the on-demand pricing model. However, this drastic price reduction does come with some caveats. Spot pricing is adjusted based on a particular instance’s supply and demand in a particular Region, as well as an AZ. […]

Protocol Independent Multicast – Networking – 350-601 Study Guide

Protocol Independent Multicast PIM, which is used between multicast-capable routers, advertises group membership across a routing domain by constructing multicast distribution trees. PIM builds shared distribution trees on which packets from multiple sources are forwarded, as well as source distribution trees, on which packets from a single source are forwarded. The distribution trees change automatically […]

Choosing the Right Cable Pinouts – Fundamentals of Ethernet LANs – 200-301 Study Guide

Choosing the Right Cable Pinouts For the exam, you should be well prepared to choose which type of cable (straight-through or crossover) is needed in each part of the network. The key is to know whether a device acts like a PC NIC, transmitting at pins 1 and 2, or like a switch, transmitting at […]

Experience Cloud licensing and sharing – Salesforce Data Management – Salesforce Certified Data Architect Study Guide

Experience Cloud licensing and sharing The license type used with Experience Cloud can have an impact on sharing and the way record access works for users. In a nutshell, the Customer Community license type doesn’t support roles, and sharing sets are used instead of sharing rules. Sharing sets are used to grant record access to any […]

Straight-Through Cable Pinout – Fundamentals of Ethernet LANs – 200-301 Study Guide

Straight-Through Cable Pinout 10BASE-T and 100BASE-T use two pairs of wires in a UTP cable, one for each direction, as shown in Figure 2-9. The figure shows four wires, all of which sit inside a single UTP cable that connects a PC and a LAN switch. In this example, the PC on the left transmits […]

THE AWS CERTIFIED ADVANCED NETWORKING – SPECIALTY EXAM OBJECTIVES COVERED IN THIS CHAPTER MAY INCLUDE, BUT ARE NOT LIMITED TO, THE FOLLOWING: Task Statement 3.1: Maintain routing and connectivity on AWS and hybrid networks. Industry-Standard Routing Protocols Used in AWS Hybrid Networks When creating a hybrid network with AWS, a standards-based routing protocol is required […]

Multicast Distribution Trees – Networking – 350-601 Study Guide

Multicast Distribution Trees A multicast distribution tree (MDT) represents the path that multicast data takes between the routers that connect sources and receivers. The multicast software builds different types of trees to support different multicast methods. A source tree represents the shortest path that the multicast traffic takes through the network from the sources that transmit […]

Switch IGMP Snooping – Bidirectional Forwarding Detection – Networking – 350-601 Study Guide

Note Changing the query interval can severely impact multicast forwarding. When a multicast host leaves a group, a host that runs IGMPv2 or later sends an IGMP leave message. To check if this host is the last host to leave the group, the software sends an IGMP query message and starts a timer that you […]
